在炎热的气候中,人从环境获得热量,要维持体温,就应该散热。体育锻炼可增加产热,并且要求有散热的渠道来维持恒定的体温。水份从呼吸道和皮肤蒸发提供了这个渠道,使热可以散发到比身体热的空气中去。蒸发一克水要吸收0.58大卡的热量。因此,水代谢在体温的维持中起着重要的作用。在炎热的气候中的水平衡可能受到 In a hot climate, people get heat from the environment, to maintain body temperature, it should be cooling. Physical exercise can increase heat production, and require cooling channels to maintain a constant body temperature. Moisture evaporation from the respiratory tract and skin provides this avenue for heat to dissipate into the hotter air than the body. Evaporate one gram of water to absorb 0.58 calories. Therefore, water metabolism plays an important role in the maintenance of body temperature. Water balance in a hot climate may be affected
